Accordingly, the matching circuit 4 prevents the signal from passing to the amplifier 5. After connecting the tested object 1, the reference oscillator 3 is turned on, while the matching circuit 4 is opened only to evaluate the error signal at a favorable moment and for an allowed time . Neither level nor nor; The duration of time is not enough to activate the Sorter 6, so an amplifier 5 is needed. The increased voltage error from 5 arrives on the Schpad amplifier circuit, 7. From the coincidence circuit 7, the signal is fed to an indicator device (not shown in the drawing), which actuates the sorting device 6. The coincidence circuits 4 and 7 are controlled by the pulses from the synchronizing generator 8. For the accuracy of the obtained values of current consumption at rated voltage in devices , and the accuracy achieved for the incandescent lamp, it should be noted that for a given value of sufficient stability, for example, 1000 mV ± 0.8 mV ,. the error does not exceed ± 0,250 / 0. 1. An automatic device for measuring electrical parameters, in particular impedances, and for sorting parts of electrical and electronic devices, comprising a comparison signal generating circuit, a control object, a reference generator, an amplifier and a sorting device, characterized in that measurements, two coincidence circuits are included in it, included at the input and output of the amplifier and connected by a common synchronous generator, named by him, 2.Устройство по п. 1, отличающеес  тем, что.схема формировани  сигнала сравнени  выполнена в виде мостовой схемы.
